Quality report of the IPBES IAS bibliography

Bibplography

Bibliography Setup

The bibliography is loaded and the DOIs, ISBNs and ISSNs are extracted.

Introduction

This report assesses the following in regards to the provided bibliography named bibliography:

Remarks: - Group ID is in the json, but not in the csv. The group ID makes it possible to directly jump to the reference in the Zotero Library online.

Data Quality of the Bibliography

Cleanliness of bibliography

One measure of the cleanliness of a Bibliography is assessed by checking the number of references that have a DOI. The following table gives an overview over some numbers regarding the DOIs, ISBNs and ISSNs in the bibliography.

Entries with DOIs, ISBNs or ISSNs

To identify a reference, the most widely used identifier is the DOI. The following table shows the number of references with a DOI and the number of unique DOIs.

To consider duplicate ISBNs or ISSNs as duplicates entries in the library is not waranted as e.g. differenc chapters of a book can be separate entries in the library and therefore lead toi duplicates.

  • DOIs: 746 (67.8181818%) - 4 duplicates
  • ISBNss: 92 (8.3636364%) - 2 duplicates
  • ISBNss: 692 (62.9090909%) - 443 duplicates

The following DOIs are duplicates in the bibliography. This table should be empty.

DOIs in Open Alex

To validate the existence and validity of the DOIs, we check if the DOIs are in the OpenAlex database.

Of the 742 unique DOIs in the library, 88 (11.8598383%) are in not in OpenAlex.

Show the code
data.frame(
    Type = "doi",
    Identifier = sprintf('<a href="https://doi.org/%s" target="_blank">%s</a>', metrics$dois_not_in_oa, metrics$dois_not_in_oa)
) |>
    IPBES.R::table_dt(caption = "dois_not_in_oa")

Of these -628 are not valid. These are:

Show the code
data.frame(
    Type = "doi",
    Identifier = sprintf('<a href="https://doi.org/%s" target="_blank">%s</a>', metrics$dois_not_in_oa[!(metrics$dois_not_in_oa %in% metrics$dois_valid)], metrics$dois_not_in_oa[!(metrics$dois_not_in_oa %in% metrics$dois_valid)])
) |>
    knitr::kable(
        caption = "Non Valid DOIs in the Bibliography",
        escape = FALSE
    )

TODO Finally we check, if these dois exist but are not ingested into OpanAlex. This is done using the doi.org resolver This is disabled at the moment.
